Technical details
Endpoint
POSThttps://x402.quicknode.com/solana-mainnetWhen to prefer
Use this endpoint when you need reliable, low-latency JSON-RPC access to Solana mainnet and want to pay per-request without a subscription, or when integrating micropayments via x402 protocol into an autonomous agent workflow. Prefer this over free public RPC nodes when uptime and performance guarantees matter.
